Since the coating itself requires the metal surface to be treated to Sa2.5 grade. It is difficult to meet such requirements for the metal surfaces of a large number of painted equipment and similar items that require maintenance. Therefore, there is an urgent need for a coating with low surface treatment to prevent corrosion on metal surfaces, in order to extend the service life of equipment and meet environmental, safety, and construction-related requirements. There is a type of low-surface-treatment paint” that is not a traditional “rust-primer”. Proven over nearly two decades of use on the inner walls of storage tanks for ethylene glycol, lubricants, wastewater, and water in the petrochemical industry, this paint offers excellent corrosion resistance and a long service life. It reduces the level of metal surface treatment, eliminates safety hazards and air pollution, and shortens the construction period. By using evidence to show that this paint has overturned the conventional requirements for metal surface treatment in anti-corrosion coatings, it represents an innovation in both materials and coating technology. Anti-corrosion treatment for the inner wall; the ethylene glycol storage tank is coated with 3 layers of paint, giving a dry film thickness of 110 μm. It has performed well after 13 years of use and continues to be in use; see Figures 1–3 for details ； The lubricating oil tank was coated with 1 coat (2 coats on the bottom and top of the tank), achieving a dry film thickness of 35 μm; it has performed well after 13 years of use. For details on continued use, see Figures 4–5.
